Semitrailer vehicle-mounted weight detection system with high measurement precision

Abstract

The invention discloses a semitrailer vehicle-mounted weight detection system with high measurement precision. The weight detection system comprises a measurement module, a control module, a power supply module and a feedback module. The measurement module comprises a laser ranging module and a strain measurement module, which are used for measuring bearing weights of a semitrailer axle part and atraction pin part respectively. The control module is used for processing the data acquired by the measurement module and carrying out calculation to obtain the bearing weight of the semitrailer; thepower supply module is used for providing stable voltage for the whole system; and the feedback module comprises a display module, a GPS positioning module, a sound-light alarm module and a GPRS module, and can achieve the functions of reminding of vehicle overload, side overturning or abnormal changes of load capacity, and uploading of information to a cloud platform in real time and the like. The invention provides a ranging module protection device which is used for guaranteeing the precision of the weight detection system. The weight detection system is simple to operate, and has the advantages of high measurement precision, easy acquisition of measured values and no need of refitting vehicles.

Description

technical field [0001] The invention relates to the technical field of semi-trailer on-board weight detection, in particular to a high-precision semi-trailer on-board weight detection system. [0002] technical background [0003] With the rapid development of the economy, my country's logistics industry has developed rapidly. Among them, road transportation occupies a considerable proportion of the transportation industry. Most of the bulk goods transported by road rely on semi-trailers. If you want to know the weight of the transported goods, you need to drive the semi-trailer to the weighbridge. To weigh, when multiple semi-trailers are weighed, they need to wait in line, which is not efficient and is limited by the location of the weighbridge, so it cannot be weighed at any time.

[0003] With the rapid development of the economy, my country's logistics industry has developed rapidly. Among them, road transportation occupies a considerable proportion of the transportation industry. Most of the bulk goods transported by road rely on semi-trailers. If you want to know the weight of the transported goods, you need to drive the semi-trailer to the weighbridge. Weighing, when multiple semi-trailers are being weighed, they need to wait in line, which is not efficient and is limited by the location of the weighbridge, so it cannot be weighed at any time

[0004] In addition, when the semi-trailer transports goods, some drivers often overload the vehicle for economic effect, which will not only damage the road surface and cause economic losses, but also cause bridges and viaducts to collapse, seriously threatening the lives of drivers and others.

Some drivers may secretly unload the goods during the delivery process for their own self-interest, or exchange or exchange goods. If there is no follower during the delivery of the goods, these problems cannot be avoided.
